Intelligence, in general, is based on the ability to adapt. When we take an IQ test, the test is a simulated intellectual environment we need to adapt to. The more ways you can adapt in that simulated world, the higher the IQ score. There are also other human social mindscapes that require adaptative intelligence. A social landscape requires human adaptation skills with the more adapted able to move up the social ladder. Even sports requires adaptive intelligences that places the body, heart and mind in a dynamic situation ,where other are also trying to adapt. This is not a standardized test but a fluidily changing mindscape. Based on that adaptation definition of intellligence, the Renassaince Men were the most intelligent since they could do it all. They could adapt quite well to all of the emotional, intellectual and physical mindscapes of their day, being socialites, musicians, artists, scientists, philosophers, warriors, athletes, etc. You put them anywhere and they will adapt with a high level of learned and innate skill.
